Scientists uncover how hormones achieve their effects
November 20th, 2007
New insights into the cellular signal chain through which pheromones stimulate mating in yeast have been gained by scientists at the European Molecular Biology Laboratory (EMBL). Similar signal chains are found in humans, where they are involved in many important processes such as the differentiation of nerve cells and the development of cancer. A sophisticated microscopy technique allowed the researchers to observe for the first time the interplay of signalling molecules in living yeast cells, and to work out how they pass on a signal through the cell. The results are published in the current issue of Nature Cell Biology. Upon release of a pheromone – a chemical signal stimulating mating...
